Final answer:
The error in the sentence is that it is a fragment and needs a verb. To fix it, add the subject 'I' and a verb like 'I woke up' which gives us a complete sentence.
Step-by-step explanation:
The error in the sentence is that it is a fragment and needs a verb. The sentence is missing a subject as well as a verb, making it incomplete. To fix it, we can add the subject 'I' and a verb like 'I woke up' which gives us a complete sentence - 'After eating three cheeseburgers and taking a long nap, I woke up with a ton of energy'.
